Football correspondent Chris Wathan watches the Swans make it four from four as they recorded their best start to a season for 91 years

But, as Swansea City flew into the rarefied air found at the Premier League’s summit, there was reason to cast minds back to the start of the 1923/24 season in that regional division.

Because as the Swansea three-and-easy win over West Brom made it a fantastic four from four in this 2014/2015 campaign, it ensured the club’s best start to a season in 91 years.

The Swans’ swatting away of West Brom with goals from Nathan Dyer and Wayne Routledge made it a maximum nine points for Garry Monk’s men from their league fixtures. Throw in the League Cup knock-out of Championship Rotherham, and no season in this part of South Wales has had more success in its beginnings.

Manager Monk smiled at the statistic but insisted it meant little; yet the fact it has been so long since a Swansea side strung so many victories together from August onwards underlines why there is plenty to be proud of at the way this campaign has kicked-off.

Not many, if any, at the Liberty would have been around to know what the performances were like as Joe Bradshaw’s team beat Luton (twice), Reading (twice) and Northampton.

But there were 20,000 who could see for themselves Swansea give their best display of this flying start - and plenty of others around the UK starting to accept this team is one to be taken seriously.

Not to continue in the upper echelons as they find themselves now, even if a top of the table clash with Chelsea after the international break has a nice ring to it.

But as a side they are firmly suggesting that talk of struggles are simply unjust in the case of a group of players ready to mix threat and sweat.

They were superb at times in this one, refusing to take their foot off Albion throats the minute they stormed into a quick-fire lead with less than two minutes on the clock. To be precise, a grand total of 87 seconds had passed by the time Dyer had the ball in the back of the net and there was no looking back from then on.

They should have had more before Routledge hit a brilliant volley to make it two on 24 minutes, and more again before Dyer wrapped things up with 19 minutes to go.

Monk knows as much, knows there’s more improvements to be made, but knows there’s not an awful lot more he can have asked from his men so far - even if he admits he’s starting to become a bit of a perfectionist.

Yet it is showing signs of rubbing off on his players. Apart from Dyer and Routledge who gave both Baggies full-backs nightmares during a sunny afternoon, there were impressive, improved showings from all after a victory over Burnley that did creak at times in the second-half.

Jonjo Shelvey has frustrated so far in being so-so, but here he was far better as he took greater responsibility with the ball while his partner Ki Sung-Yueng was ready to throw himself at the ball as well as play intelligently with it. If Swansea’s attack killed West Brom, their work off the ball ensured there was no return from the grave.

Wilfried Bony will shake his head at some of the missed chances to have stretched this scoreline, but his hold-up play was perfect and one of the reasons the widemen got so much joy was because so much frightened attention was being paid to the Ivorian in the middle.

And then there was Gylfi Sigurdsson who, in this fourth win from four, made it a personal joy of six. The half-dozen goals scored by Swansea in the Premier League have all directly involved the Icelander: one goal scored at Old Trafford and five assists.

There was an element of luck about boosting his statistics in the first two, but there was nothing fortuitous about the finishing that followed.

Angel Rangel marked his centenary of Premier League appearances with a venture forward seen in pretty much every one of the 100, the ball ending up in a one-two between Dyer and Sigurdsson with the latter’s back-heel sending the winger into the box.

A slip from a panicked Jonas Olsson set up the chance, Dyer finished it as he skipped past the onrushing Ben Foster and found the net from a tight angle.

The luck involved in the second was more down to West Brom’s bad defending,

Chris Brunt inexplicably rolling the ball to Sigurdsson on the edge of the box after sustained Swansea pressure. The cross was only half-headed away by Craig Dawson, the ball dropping to Routledge on the edge of the area whose volley was one to watch. Think Mark Hughes against Spain; not quite as spectacular but just as special.

Bony had gone close before a Routledge delivery aimed for his head saw Olsson try to get his own head to it, the ball looping behind him and over Foster but onto the Albion bar.

And all that was offered in return was one Brown Ideye shot from close range after turning Jordi Amat and one from 40 yards that had teammates turning on him. Neither troubled Lukasz Fabianski.

A Routledge half-volley was unlucky not to hit the roof of the net and Dawson made up for his earlier error with a vital interception to frustrate Bony further, his agitation with himself increasing as Dyer put one across the box for him.

A penalty could have been claimed when Andre Wisdom, with his hands by his side, inched his arm to keep out a Bony indirect free-kick for a Dawson back pass.

And just when they thought Swansea were turning down the tempo in the final 20, so came on Jefferson Montero who burned strips in the grass and put one on a plate for Bony to sky from close range.

A third would come, though, with 71 minutes on the clock when Ki slipped in Sigurdsson whose flick pass sent Dyer racing away and his calm shot beat Foster.

A third goal in a week for Dyer, a fourth win for Swansea and the best start in 91 years. Swansea’s numbers game is adding up to some pretty impressive reading.
